Toshiba HD ready TV ct 90158 makes high pitched sound

A high pitch sound can be a capacitor losing power it would sound a bit like a fire work. most have back up on the board but it put more pressure on them the more times you use the tv. would check them and replace. all of them can be 5 in a row in some models.

Mitsubishi VS-60805 Rear Projection won't operate in HD mode with Cable Box

Since this is an older first generation (1999) HD TV it may not be compatible with newer HDTV receivers because the standards back then were different - Make sure the HD cable box is plugged into the HD component inputs on the back of the TV (not the DVD inputs) and that the menu setting on the TV is set to DTV (not RGB) video. This TV will only accept 480i and 480p signals on the DVD input. Also the HDTV input will only accept 480i,480p and 1080i (it will not work with a 720p signal,make sure your cable box is not set to that mode)

We've had our 32" Vizio TV for about 4 months now and up until about 2 weeks ago, everything was working fine and all channels came in. Now, we only get about a quarter of the channels that we used to...

go to menu settings, find add/delete channel or programming or tuning. There should be an option that says "autoprogram" select this option and let the program run thuroughly. It will read and install all available channels. Do make sure tv is set to CATV and that it is NOT set on AIR.

Video is taking on a red tint which is getting worse over time

check the cable connections. look at different inputs. VGA and Component cables have the colors split, so if it's turning red, green, or blue; it's likely a cable or connector.

Recently installed two Philco TB100HH9 Converter boxes. Both worked well at first then both lost a major local TV station within days and cannot reprogram it into the box. Have two other TV's without a...

I just had a similar problem with this box - For the first month or two, I got the local NBC affiliate (KING-5 in Seattle) just fine on 5.1, then, after fiddling with my antenna setup, I lost it completely - NOTHING I could do would get it back. I tried a bunch of stuff - Multiple types of antenna, adding an antenna amp box, a handful of "homebrew" antennas - Nada. Yet all my other channels came in fine (although a couple were right on the edge - This box seems to need a "17" or higher on the signal strength - Some of my channels were reading in the 15-18 range, and suffering the "blockies" and sound dropout)

After hitting, found out that the KING digital signal is actually broadcasting on channel 48. Punched in 48.1, and there it was, clear as a bell, using nothing but a "wick" antenna (Basically, strip 4-1/4 inches of the outer braid off one end of a piece of co-ax cable, leaving the center wire alone, then plug the other end into the box) getting me a 23 signal strength. But a second or two later, the box is displaying "5.1" - Weirdness...

Reconnected a near top-of-the-line Winegard Yagi/Log-periodic antenna - VERY directional, and has some gain all by itself - and the signal jumped above 50.

Still couldn't "channel-up/channel-down" or punch in "5.1" to tune it, though - Channel 5.x was a "dead zone" as far as the box was concerned.

Re-did the "autoscan", and now, it's back to normal - I can channel-up/channel-down to it at 5.1, or I can punch it in as 5.1, or I can punch it in as 48.1, and it's all good.

So, try re-doing the auto-scan. Worked for me...

Does the Tv pick up a signal ? ( picture/sound ) If not, you may have a tuner problem as the screen will default to blue with no signal apparent. Could also be a cable problem. Hope this helps

Please Help!

A chirping sound from a TV set is the switch mode power supply trying to start up, but gets shut down because of a major short inside the set or in one of the circuits.. Most likly in this set, the horizontal output transistor is shorted because of a defective flyback transformer. Thats whats the common problem is with this set. A repair like this, if this is the only parts that are bad, will run you about 300 to 400 bucks or so. In some cases, not many but a few times, I have seen poor solder connections on L401 cause the horizontal output transistor to go bad. There are no user replacable parts inside this set, so please play it safe and seek out a pro to assist you in this repair. Good luck PS Please do not forget to rate this thread.
